Is Duolingo free forever? Yes — the core lessons are free, and Duolingo has kept them free since it launched in 2011. Every lesson in every course is free, with no time limit and no expiry date. But “free forever” does not mean “everything forever, with no limits”. The free plan has limits, and those limits have changed over time. This article explains what “free forever” actually means in 2026, what has changed, and what could change next.
Free Duolingo in 2026: all courses and lessons free, with ads and a daily energy limit on mobile (25 energy a day on most accounts). The web version has no energy limit. Super removes the limits; it never adds lessons.

What “Free Forever” Means
“Free forever” is Duolingo’s founding promise: language education should be free for anyone with internet access. In practice it means three things. First, every lesson is free — Duolingo’s own help centre says it offers the same lesson content to all users, free or paying. Second, there is no time limit — the free plan is not a trial, and it does not expire after a week or a month. Third, no language is locked behind payment — all 40+ languages, plus the music and maths courses, are open to free users.
What “free forever” does not mean is that every feature is free, or that the free experience never changes. Duolingo is a freemium app: the core lessons are free, and the extras — removing ads, removing the daily practice limit, offline lessons — are paid. The line between “core” and “extra” has moved over the years, and that movement is the honest answer to the question in this article’s title.
What Free Users Get — and What They Do Not Get — in 2026
| Free in 2026 | Not free in 2026 |
|---|---|
| Every lesson in every course (40+ languages) | Ad-free lessons |
| Streaks, XP, leagues, leaderboards, gems, achievements | Unlimited energy on mobile (25 a day on most accounts) |
| Explain My Answer — free for all since 1 January 2026 | Offline lesson downloads |
| Practice Hub — free for all since 18 February 2026 | Full personalised practice and progress quizzes |
| Unlimited lessons on the web (no energy limit) | Unlimited Legendary Level attempts |
| Music and maths courses | Monthly streak repair (free users use Streak Freezes) |
| Daily goals and progress tracking | AI Video Call (rolling out to Super by end of 2026) |
The most important row in that table is the energy limit, because it is the limit free users feel every day. On most mobile accounts you start with 25 energy, every exercise uses some whether you answer right or wrong, and when it runs out you wait for it to recharge, watch an ad, or spend gems. Most free users get about 2–3 lessons — roughly 15–20 minutes — before hitting it. Some accounts still have the old hearts system, and the web version has no energy limit at all, so a free user on a computer can study far longer than a free user on a phone.
It is also worth saying what has got better for free users, because the story is not all limits. Explain My Answer used to be a top-tier paid feature; it became free for everyone in January 2026. The Practice Hub followed in February 2026. The free tier in late 2026 is more generous in those two places than it was a year ago.
How the Free Plan Has Changed Over Time
| When | What changed for free users |
|---|---|
| 2011 | Duolingo launches with the “free forever” promise. Core lessons completely free, no paid plan at all at first. |
| 2017–2019 | Ads and the hearts system arrive on the free plan. Mistakes start to cost hearts; free users can run out mid-lesson. |
| June 2022 | Duolingo Plus is renamed Super Duolingo. The paid plan’s job stays the same: remove ads and limits. |
| 2023 | Duolingo Max launches above Super, with AI features (Explain My Answer, Roleplay, Video Call) as paid extras. |
| Mid-2025 | Energy starts replacing hearts on mobile. Every exercise now costs energy, not just mistakes — free daily practice shrinks to about 2–3 lessons for most users. |
| Jan–Feb 2026 | Explain My Answer (1 Jan) and Practice Hub (18 Feb) become free for everyone — two paid features move the other way, into the free plan. |
| Nov 2026 | New Max sales stop; Video Call moves into Super. The free plan itself does not change — the paid tiers above it are reshuffled. |
The pattern is clear: the lessons have always stayed free, but the limits around the lessons have tightened and loosened over time. Hearts limited mistakes; energy limits everything. At the same time, features have sometimes moved from paid to free, as Explain My Answer and the Practice Hub did in 2026. Anyone who tells you the free plan has only ever got worse — or only ever got better — is leaving half the story out.
How Duolingo Pays for Free
Free lessons are not free to run, so how does Duolingo afford them? Three revenue streams carry the cost. First, ads: free users see ads between lessons, and that advertising is the backbone of the free tier. Second, subscriptions: the minority of users who pay for Super (and, until November 2026, Max) fund the lessons for everyone else. Third, the Duolingo English Test: a separate paid product — $70 a test — that brings in income from test-takers and institutions, not from language learners.
There is also a smaller stream: in-app purchases such as gems and Streak Freezes. And one thing the old version of this article got wrong: it listed “data insights” sold to researchers as a revenue stream. No reliable source confirms that, so it has been removed — there is no evidence Duolingo funds the free plan by selling its users’ data.
This funding model is why “free forever” is credible as a promise but not a guarantee. As long as ads and subscriptions cover the cost of the free tier, the lessons stay free. If that maths ever stopped working, Duolingo would face a choice: tighten the free limits further, or charge for lessons. So far it has always chosen the first option — tightening limits, not charging for lessons.
Will Free Duolingo Stay Free?
The honest answer: the lessons almost certainly will, but the free experience around them will keep changing. Nobody outside Duolingo can promise what the company will do in five years, and this article will not pretend otherwise. Here is what we can say from the evidence in 2026:
- Free lessons are core to Duolingo’s identity and its business. The free tier is where new users arrive; charging for lessons would cut off the top of that funnel. Duolingo’s own help centre still says the same lesson content goes to every user.
- The paid tiers are where the change happens. In 2026 the change was Max ending and Video Call moving to Super — the free plan was untouched by that reshuffle.
- Limits are the lever Duolingo pulls, not lesson pricing. When the company wants more revenue, it has tightened the free experience (hearts, then energy) rather than putting lessons behind a paywall. Expect more of that kind of change, not a sudden price tag on lessons.
- Features can also move the other way. Explain My Answer and the Practice Hub became free in 2026, which shows the line moves in both directions.
What should you do with that? Do not build a study plan that depends on the free plan staying exactly as it is today — the energy limit arrived with little warning, and another change could do the same. But do not pay for Super out of fear that lessons will suddenly cost money either. Pay for Super when the free limits are what slow you down today, not when you worry about what might happen tomorrow.
Frequently Asked Questions
Is Duolingo really free forever?
The lessons are free with no time limit, and they have been since 2011. “Forever” is a promise about lessons, not about every feature — ads, the energy limit, and paid extras have always been part of the deal, and the limits have changed over time.
What is free on Duolingo in 2026?
Every lesson in every course, streaks, XP, leagues, gems, achievements, Explain My Answer, and the Practice Hub — plus unlimited lessons on the web version. What is not free: ad-free lessons, unlimited energy on mobile, offline lessons, and unlimited Legendary attempts.
Has Duolingo ever charged for lessons?
No. Lessons have always been free. Duolingo has charged for removing limits and for extras, never for the lessons themselves.
Why does Duolingo keep making the free plan more limited?
The free plan pays for itself through ads, and the company earns more when some free users upgrade to Super. Tightening the free limits — hearts, then energy — pushes more users toward paying, while keeping the lessons themselves free.
Is the free plan enough to learn a language?
It is enough to start and to build a daily habit, especially on the web where there is no energy limit. For serious daily study on a phone, the energy limit is the real obstacle — most free users get about 15–20 minutes a day on mobile. Duolingo alone, free or paid, takes most learners to around a basic level; it is a starting point, not a complete course.
The Bottom Line
Yes, Duolingo is free forever — in the sense that matters: every lesson is free, with no time limit, and that has not changed since 2011. What changes is everything around the lessons: ads, the energy limit on mobile, and which practice features are free. In 2026 the free plan is tighter on mobile than it used to be, and more generous in two places (Explain My Answer and the Practice Hub are now free for all). Expect the limits to keep shifting — but do not expect a price tag on the lessons themselves.
